In 2020, due to the COVID-19 pandemic, the number of pilgrims allowed to perform Hajj was drastically limited to only 10,000 people. This was a significant reduction from the nearly 2.5 million pilgrims who performed Hajj in 2019, as the pandemic led to strict restrictions to ensure safety and prevent the spread of the virus. The 10,000 pilgrims were selected from residents within Saudi Arabia who met specific health criteria. Thus, the number of pilgrims performing Hajj in 2020 was approximately 10,000. This information highlights the impact of the pandemic on one of the largest religious gatherings in the world.
